. . .at getting good grades. School does not necessarily teach anything "useful" or that can be transferred directly to living life better. It is an experience and one has to "think" in particular ways, learn to reason things out and argue one's position, etc. For a pharmacist or pharmacy tech, one would learn useful things like chemistry and how to do do certain parts of one's job.

How much one gets paid is not necessarily related to one's schooling or choice of career. We all know of starving artists/writers and those who "lucked" out and got on Oprah's reading list or were "discovered" and became rich and famous. I think the most important thing is doing what YOU want, not what someone else wants for you or thinks is best for you, etc. You are the only one who is living your life and doing what someone else wants you do is not living your own life, making your own decisions, etc. and can be a waste.
